Improvement in windmills



@anni @time WILLIAM I. TUSTIN, OF SAN FRAMISGO, CALIFORNIA.

Letters Patent No. 97,136, dated November 23, 1869.-

IMISROVEMENT IN WINDMILLS.

The Schedule referred to in these Letters Ptent und making part of the same.

To all whom it may conce/rn Be it known that I, WILLIAM I. 'lUs'rrN, of the city and county of San Francisco, Stateof California, have invented an Improved NVindmill; and I do hereby declare the following description and accompanying drawings are sulioient to enable any -personskilled in the art or science to which it most nearly appertains,

to make and use my said invention or improvement,

, direction or at the-angle requisite for producing the,

required speed.

It also consists of a device, which is attached to the lower end of the vertical shaft, which support-s the wheel, and which is connected with the turn-table by a rod, by means of which the wheel may be turned to the angle required, the operation heilig performed by means of cords, within easy reach of a person standing upon the ground.

Referring to the accompanying drawings, ibrlning a part of this speciticationy A is the frame, which supports the mill, and

BB', the cross-timbers, into which the lower end of the vertical hollow shalt G steps.

rIhe guide-vane or rudder I) is secured firmly to the top of the shaft C, by any suitable means, so as to be stationary, and a circular flange, a, which forms the bed of the turn-table, projects at right angles from its top.

The crank-shaft b, to which the wheel E is attached, turns in boxes on the circular table F.

This circular table is provided with a segmental flange, e, which projects downward from the outside rim, the inside of which is toothed, forming a segment-al rack.

This circular table is placed, as before hinted, upon the circular flange a, on the top of the shaft, thus forming a turn-table.

On the lower end of the vertical shaft C, is a spin- (lle, or hollow step-gudgeon, which steps into the' metal plate f, in which the bearing of the shaft rests. YOn this spindle is placed, loosely, a pulley, G, having a small pinion, g, secured to its upper face, around the spindle.

A connecting-rod, I, extends parallel with the shaft C, having, at its lower cud, a gear-wheel, Q; and on its upper end a pinion, i.

The upper end of this rod passes through thc rudder-bar, and the pinion fi engages with the segmental rack e, while the wheelon the lower end engages with the toothed pinion g, on the pulley G, so that by turning the pulley, the table Fis turned around so as to stand atany required angle to the rudder.

Directly under the pulley G, is a clutch-ring, K, which is secured to the spindle, so as to be stationary, and upon which the pulley G rests when not elevated by the lever L.

Above the coupling, and on the underl side of the pulley G, are projecting lugs or pins, n, which, when the pulley drops by its own weight upon the. coupling, engage with it, and prevent the pulley from turning, thereby securing the wind-wheel in its required position, relative to the line of the wind, at all times, even should the wind veer the rudder to a different position.

An endless cord, c, passes around the pnl-ley G, and over the small pulleys N on the cross-bar' B', and thence, passing downward, it passes around the pulley O, to which is attached a weight, l. y

A cord, fr, is attached to one end of a curved lever, L, which is secured upon one of the cross-timbers, B, directly under the pulley G, so that by pulling downward upon thc cord, the opposite end of the ounved lever is elevated, carrying with it the pulley G, and clearing it from the clutch-coupling, so' as t() mlm it to turn as may bc required. i

After the pulley has been freed from the coupling K, by drawing downward upon one side vof the endless cord fu, the pulleyis turnethcausiug the pinion t to operate the gear-wheel Q and rod I, and through the rod, the circular table F, thus placing the windwheel at any desired angle to the wind; and by drawing downward upon the opposite side, it is drawn back into line with the rudder, when, by letting go of the cord fr, the pulley G will fall by its own weight, and engage with thecoupling below, thus ixing the ,wheel at the desired angle to the rudder, so that it will have the saine relative position tothe wind, no difference from lwhich direction the wind comes, or to which it changes.

By this device, the speed of the wheel can easily be regulated by any person standing upon the ground.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is-

l. The table F, with its projecting segmental rack e, turning onthe flange a, in combination with .the wheel E and rudder l), substantially as and for the purpose herein described.

2. The vertical connecting-rod I, with its genr- Wheel Q und pinion i, when used for connectingguljustine-gears on the lower end of the vertieal shf't O, either with the table F, or directly With the wheel E or ruldex' D, substantiully as and for the purpose herein described.

3. The pulley G, with its toothed pinion g, and

under-projecting lugs or pins 11, the same beine,r raisedv by means of the curved lever L, and operated by the endless cord o, passing over pulleys N `and O, and Ikepttaut by the weight P, substlntially as described,

for the purpose herein set forth.

In witness whereof, I har/e hereunto set my hand and seuil.

WILLIAM '1. TUSTIN. [u s.]
